When you are waiting in line at a fast food joint, the amount of people in the line combined with the number of open servers and time are all statistics. Basically the statistics is the time it takes for each person to be served and how much output the restaurant could get.
I learned it in productions and operations which deals with all statistics. You could apply this model to how much time you spend waiting in line based on your productivity. For instance, whenever I wait in line, I read articles on my pocket pc phone. By doing this I am consuming 5 more articles a day and thus increasing my productivitiy and efficiency in digesting knowledge.

Statistics In Everyday Life

You can apply statistics to just about anything that is uncertain. Getting a handle on events and things that are not one hundred percent certain is what statistics are all about.
The range of difficulty in statistics is wide. It ranges from simple probability, like what are the chances of thowing a seven on a pair of dice, to estimating the rate of radioactive decay. In every day life, you can use rudamentary statistics to:
1. Determine how soon you need to leave home to make an appointment on time with a high degree of confidence.
2. Decide whether or not to take an umbrella.
3. Try to draw to that inside straight.
4. Buy, sell, or hold a common equity stock.
5. Decide which lane to drive in on the freeway; so as to minimize chances of getting pulled over by the highway patrol.
6. Decide which airline to take to Disneyland; so as to increase your chances of departing on time.
And on and on. The point is this, whether you know it or not, you're probably using statistics daily. For example, the airline use...do you look up the percentage late departures for the various airlines and take the one with the lowest percentage? If you do, that's decision making based on statistics.
Or, here's one...how do you choose which line in the supermarket to step into? You pick the shortest line to start with in all liklihood. Why? Because, statistically speaking, that is the service line that will have the least waiting time. (That results from a branch of statistics called queueing theory).

Ok, here is one. Let's say you are on a jury in a murder case, in a city of 4 million people.
Let's also say that it is a DNA case, and the test being used has a 1 in a million accuracy (meaning that, on average, only 1 in million people would match a particular strand)
The District Attorney says: all we have is the murderer's DNA. The defendant's DNA matches. We know that the chance that the murderer could have this DNA is 1 in a million, therefore, the defendant is almost certainly guilty.
The Defense counters: All you have is the murderer's DNA. We know that, on average, 4 people in our 4 million strong city could match, and the defendant is only one of them. Therfore, there is a 75% chance that he is innocent.
In this case, the Defense is correct. We want to know the chance that the defendant is guilty, given that he matches the test DNA.
Would you have been taken in by the DA? We have quite a difference between a 1 in a million, and 75% chance of innocence. Considering how often DNA is used as the *sole* criteria for convicting someone, I would put this example as both fairly common and very scary.

Casino games, craps, poker, blackjack, roulette, red dog, baccarat, etc.
It is also used in wireless technology (i.e. cell phones, wireless routers, etc.).. Let's say you are in a coffee shop surfing the net on a wireless wi-fi card. The card receives data in the form of bits (a sequence of 0's and 1's). However, when the data is received it is actually 0 or 1 +- some noise factor. Let's say a data value of .85 is received. Probability is used to determine the probability of receiving .85 if a 0 is sent, and the probability of receiving .85 if a 1 is sent. Using that probability your wi-fi card determines what sequence of data was more likely sent.

Take an average of anything; calculate the odds and convince yourself not to buy a lottery ticket
